I used a Miller 110v Mig Welder with argon gas. I am not knowledgeable when it comes to temp and speed of wire. All my enjoyable welding experience comes off my cousin's welder and he always set it up for me. He also had a battery operated welding helmet which allowed you to see the material but it would switch to dark when the welding starts. Big picture.....I need to learn more. Anyways, I kept it lowest heat setting and around 22 for the speed. I finally got a better feel for it today when I welded the resonator onto my transition.
Yesterday, simply welding the 3" piece to the 3" end of the transition took me some time. I ground a 45 degree edge on both pieces and went to town on the welding. I was going "on-off, on-off, on-off" but my dad thought I was smoking crack. He took his turn and he was burning holes! So I took over and put the temp much lower and sped it up. I kept laying down welds and then ground it down. Sadly.....I had 4-5 pin holes that I had to go back and weld then grind. Today went easier.
